Thought Eater Butcher (Basic Lore)

Thought Eater Butcher (CR 28)
Pure Evil - Large - Outsider
A Thought Eater is one of the oddest and most hated of all monsters. They appear out of nothing, surrounded by a wavy distortion in the air as if they are surrounded by massive heat-ripples (even though they are cold), and they hover a few feet above the ground. They appear emaciated, even skeletal, ribs and pelvis standing out against translucent ectoplasmic 'skin'. Their heads are ghastly, a large round skull with huge eye sockets that may or may not evidence eyes, and a vast jagged beak on the front. Their skeletal limbs are stunted, and they have a paddle-like tail and wide-flippered feet as if they are meant to swim. It is speculated they live in the Ether, and after sensing prey in the Prime they force their way into our world to feed. Their feeding is ghastly, as they create sucking vortexes that target spell casters and feed on their very minds, damaging their intellects, aura, and bodies in equal measure. Once they have fed upon a hapless caster enough, they will then switch their attacks around, leaving a frightening mental numbness behind. Thought Eaters are well-suited to feed on spellcasters, as they have defenses against the effects of spells and even destroy a caster's ability with spells at the same time. If you are attacked by these awful things, stab them. Spells are of little use. 'Butcher' is the term used to describe this aggressive and dangerous evolution of Thought Eaters. Thought Butchers, as they are often called, are massive things, far larger than Slayers or Hunters, and they look more fleshy, their forms seeming 'filled out' with opalescent tissue that somehow gives an impression of...wrongness. The weird spatial distortions that appear around all Thought Eaters when they manifest are nearly invisible with Thought Butchers, but survivors of their attacks emphasize the creeping insanity of their presence is far stronger, despite being nigh-impossible to see. Butchers attack with absolute savagery, their eldritch powers dreadful, and even survivors of their attacks are often so devastated they require rest to recover their auras. Approach with caution, fight with no mercy, and beware, that Thought Butchers often have allies as terrible as they are.
